Polyethnic-1000 Advancing cancer genomics by studying ethnically diverse patient populations in New York Fieke Froeling1,2, Nicolas Robine1, Benjamin Hubert1, Michael Zody1, Dayna Oschwald1, Harold Varmus1,3, Charles Sawyers1,4, David Tuveson1,2, On behalf of the NYGC P1000 Consortium 1 New York Genome Center, 2 Cold Spring Harbor Laboratory, 3 Weill Cornell Medicine, 4 Memorial Sloan Kettering Cancer Center Background Stage I: retrospective, feasibility study • Known ethnic differences in cancer incidence and mortality. • Central IRB approval (BRANY) with waiver of informed consent • In most cases, the causes for these variations are multi-factorial, however little • Sample requirements: remains known about the molecular attributes. - Self-identified non-white cancer patient > 18 years old • Advances in sequencing technologies have revolutionized approaches to the - Tumor sample no older than 2016 prevention, risk assessment, early detection, diagnosis, and treatment of cancers. - Estimated tumor percentage at least 50% • However, many ethnic groups, especially non-European populations, continue to be - Size of the tumor needs to be at least 0.5 cm x 0.5 cm significantly under-represented in cancer research, including clinical trials, and have - All samples will be de-identified before submission to NYGC not received equal benefits in clinical practice. • Central pathology review at NYGC by P1000 pathologist: - 30 samples reviewed, ~70 in pipeline for shipment to NYGC from total of 14 different sites Our current knowledge about cancer risk, biological behavior and response to - Diverse range of tumor types and ethnicities treatment has primarily been derived from patients with a European ancestry. • Tumor only WES and RNAseq (Illumina Novaseq) - Genomic ancestry via “Ancestry Informed Markers” Aim - Variant calling, allele-specific expression, alternative splicing, fusion discovery Polyethnic-1000 aims to study the genomic landscapes of cancer in the ethnically diverse - HLA typing population of the greater New York City area and thereby: • Data sharing limited for stage I: 1.

Stage II and III: prospective generation of the Polyethnic-1000 Methods database • Coordinated by the New York Genome Center (NYGC), leaders of the New York City • The study will enroll any patient with cancer and a self-identified race/ethnicity of non- cancer research community joined together to create a dynamic research platform white (stage II). However, specific research proposals will address questions in particular involving the NYGC, academic centers and partnering hospitals in the New York City tumor types with known worse disease outcomes in certain ethnic groups (stage III). region (Figure 1, 2). • Data generated will be integrated with similar national and international initiatives (AACR Project GENIE, ICGC ARGO, and others). • The project is designed to take place in 3 stages (Figure 3): a retrospective feasibility study (stage I) to enable the start of a prospective pilot (stage II) and expansion study (stage III), which will include selected research projects within the Polyethnic-1000 Figure 2.
